Heat treating of beryllium copper is a two-step process, which consists of solution annealing and age hardening (Table 2). Solution annealing is often done by the mill and involves a high temperature soak at 1450°F (790°C) for the high strength alloys and 1650°F (900°C) for the high conductivity alloys. Excess time or temperatures may cause ...
